System, method, and apparatus for data processing

A data process method used for a system including one or more data process apparatuses, the data process method comprising the steps of:

• storing, in a user data storage unit, user information of one or more first users including user identification data;
• storing, in a guest data storage unit, second address data in correspondence with the user-identification data of the first user as a logging target, the logging target being data pertaining to a guest user different from the first user;
• and
• storing, in an output data storage unit, output data in correspondence with the user-identification data or data-identification data;
• receiving a request data including the output data via a network;
• determining whether the request data is for outputting the output data by the first user or by the guest user and specify the user-identification data of the first user in correspondence with the second address data included in the request data when the request data is for outputting the output data by the guest user;
• notifying the data-identification data via the network;
• and
• transmitting the output data corresponding to the data-identification data received from the guest user via the network,
• wherein the storing of the output data includes storing the output data in correspondence with the data-identification data and the specified user-identification data of the first user in a case where the request data is for outputting the output data by the guest user, and
• wherein the specified user-identification data is included in log information that is generated by the one or more data process apparatuses when the guest user outputs the output data by using the data-identification data.

A data process apparatus comprising:

• a guest data storage unit configured to store second address data in correspondence with user-identification data of a first user as a logging target, the logging target being data pertaining to a guest user different from the first user;
• a reception unit configured to receive a request data including output data via the network;
• an identification unit configured to determine whether the request data is for outputting the output data by the first user or by the guest user and specify the user-identification data of the first user in correspondence with second address data included in the request data when the request data is for outputting the output data by the guest user;
• a notification unit configured to notify the data-identification data via the network;
• and
• a transmission unit configured to transmit the output data corresponding to the data-identification data received from the guest user via the network,
• wherein in a case where the request data is for outputting the output data by the guest user, an output data storage unit is configured to store the output data in correspondence with the data-identification data and the specified user-identification data of the first user, and
• wherein the specified user-identification data is included in log information that is generated by the data process apparatus when the guest user outputs the output data by using the data-identification data.
